How to Beat Cerberus First have scan equipped (this is extremely important). Stack up on mega potions, potions and Elixirs. When you enter the arena, go up and attack Cerberus. Soon he'll jump up. He can't reach that far but don't run ether run up onto the seats/stands, or right when he's coming jump up. Soon he'll start drooling. Start running and keep jumping. He'll start firing fireballs soon. When your health goes down use cure, mega potion, or potion. Alternatively jump up when Cerberus is coming down from his jump. Remember to keep attacking. Keep doing this until he's dead.
Easy Level Gain At the beginning of the game, when you are being asked questions, always chose the top answers to gain levels more quickly. If you chose the bottom ones you will level up slower.
Fight the final boss You must finish the story until the Final Rest of The End Of The World before you fight with Ansem. You can go out using the Save Point. In Agrabah, talk to the flying carpet and it will take you to the desert. It is found inside Aladdin's house. In Neverland, go to the room that has a Save Point. Use the Save Point to switch Peter Pan with Donald or Goofy.Talk to the Twinkle Bell. Then, you can fly to The Clock Tower and fight with The Phantom. Prepare yourself first because the boss is devious. Make sure you bring the right item.
Different Ending Finish the game and get all Keyholes, 99 Dalmations & the Hades Cup.
Get lots of money Go to Deep jungle and find a heartless monkey (the yellow one). If you defeat it you can get a lot of money. However you get more money if have already first battled with Ansem (the first time).
Quick reset To do a quick reset in Kingdom Hearts press and hold L1+L2+R1+R2. This is much easier than resetting the console. Note that this will send you back to the menu.
How to beat Riku After 4 hits he does a flying kick move, make sure you dodge it because it does major damage. Also make sure not to fall of the ramp because you'll lose the match if you do.
Fastest Way of Levelling Up (at the beginning) When you start out the game and you choose whatever you want. Talk to Kairi, and go up to Wakka. Talk to him and he'll ask for a round to fight. Choose "Sure I'll play". Keep your distance, when he throws you the ball, attack. Make sure to time it correctly and to stay at an angle so you can "tech" and not hit him. This way you will get points more quickly, and practice your timing. It saves a lot more time then fighting them one by one, or three on one, so in five minutes you'll should have 25 points or more of experience.
Rare Truffle Victory Go to the Colloseum, for the Hercules cup. Go to the annoying monster that disappears as soon as you hit it. Target the truffle and the first time you hit; it'll go flying into the air. When this happens, jump and attack it once. It'll pop right back up into the air. Repeat this and make sure it doesn't hit the ground or it will disappear. It takes a long time to kill it, but it's worth it. This monster gives around 4,000 experience points, which is more than any other normal monster in the game. Also it's great for levelling up!
How to beat Sephiroth Go to the colisuem, and the platinum match. You have to face the almighty Sephiroth, who is harder than the final boss. Equip Strike Raid and the Oathkeeper Keyblade. Cast the shield and use Strike Raid whenever you can. Once his life starts to go down, he uses his angel attack which drains all health points and magic points. Stop him before he uses it. Futher on he'll power up and go ballistic. Just keep your life up and use strike raid. Don't let him use the angel attack or you'll die. He gives the most experience points in the entire game (18,000). You'll level up every time you beat him.
Easy Level Up On Destiny Islands talk to Tidus and fight him, if you time it correctly you can hit his rod to give you two experience points. This is the quickest and easiest way to level up.
Early experience points and unlimited potions For much easier experience points, and a free potion for each victory, fight Riku before you turn in your rope, cloth and logs. If you chose shield (or sword) as strength at creation, and magic as your weakness this should be no trouble. When he stands back and taunts you, hit him three times (he'll parry) and then step to the side. He will do a spin attack, missing you, and you can then do a three hit combo on him. It is worth five experience points for defeating him, plus the potion. If you parry an attack of his it is an extra two experience points. Just remember, if you use your first potion you will need to equip new ones you have won before entering a new fight. After a few tries or levels you won't even need potions and can start letting them stack up. Once you turn in the logs, rope, cloth and rest for the night you can no longer fight him, so level up while you can!
Tips to beat Sephiroth How to beat Sephiroth easily: Rule number one: You really need elixirs on this battle.
Rule number two: You don't need a high level but I recommend level eighty or higher. He will start the battle walking and swinging his sword toward you and sometimes he makes a fiery wall around himself. You can jump and smack him in the head once he starts losing his real life. If you hit him you will see his life is not depleting you are wrong, it's only because he has too much life! Once his life turns pink he will start running toward you and he will make a attack called Sin Harvest (if you listen carefully he says "Sin Harvest"). As soon as you hear those words run towards him. Hit him. If you are too late (indicated by a red symbol appearing), you have run too far. When the attack is over it will deplete your magic points and health points unless you have the Second Chance Ability. So use a elixir before he gets you. Also he will make an attack that hits you a thousand times. This time you can use Strike Raid which will make you invincible when the attack in progress. When his life turns yellow a black aurora will appear, wilting him. He will throw lots of meteors and they will start surrounding him. Run around in circles so the meteors can't hit you. When the meteors stop he will fire a huge one towards you. From this point on he will no longer use "Sin Harvest" but he will be much faster. When he swings his sword he will shoot dark energy balls. You should jump and smack him in the head. Abilities needed: 2nd chance, magic points, Haste & Rage and Strike Raid. Try learning his pattern and come up with your own strategy.
